you will have traction issues on the track...you will also have to run a 27+" tire at the track because if you run a 26" tire you will top out 3rd gear at 108 MPH. im talking about a auto with 4.10 gears.
#92
I have an 08 stang 4.6lt auto. I would like to hear more from the guys with the same mainly auto, about their switch from the 3:27 / 3:32 etc to the 4:10's. I worry more about creating a whine or some sort of an unwanted noise due to putting in new gears. Sorry, but thats my kind of luck. Anyway like to hear from those 4.6lt auto people.

That's why you get the bearing kit. It's not always needed, but I always recommend it. Since your car is in '08, unless you've really been driving that thing like a bat out of hell since you got it and being rough and tough on everything, even then you still might not need the bearing kit...but I still encourage them.
Also, what kind of driving do you do? If you don't do a bunch of city driving, you might try 4.56s? I've heard that's crazy, but I've never seen them in action.

Gear choice has to deal with tire size,traction,power,goals for the car. Bolt on car like yours with no power adders, I would go 3.73's.

2v and 4v is only in reference to the 4.6 and 5.4L modular motors, not the old push rod motors like your 302. 2v means that it has only 2 valves per cylinder, one intake one exhaust. 4v is 4 valves per cylinder with 2 intake and 2 exhaust valves. Also the new 3v GT cars have 2 intake and 1 exhaust valve.

Thanks wikipedia

No one pays attention to it and always asks questions that we have answered a million times, anyway. It's useless unless the mods lock every gear thread made that isn't asking a genuine unasked question and tell them to read and post any other relating questions here.
#101
No the v6 cars have a very wide rang of gear ratios as did the 96-98 GT models. You could have anything from 2.73,3.08,3.27 in your rear end in a GT or V6 in those model years stock. I believe most v6 cars had the 2.73 gears from what I recall.
#102
yes 94-98 v6 mustang have 2.73 while the 99-04 V6 mustangs have 3.27 gears
#103
i thought i read somewhere that the 99-04 rear was not as wide as the 94-98. is that right? and i did find this to identify what i have by post #4 on
http://mustangforums.com/forum/gener...ear-ratio.html
i've got 2.73, no tloc, what i would want to look for in a junkyard would be the axle code E with traction lock, that would give me 3.27's but that brings me back to my other question, what years i can get one off of?

Hi all,
The gear calculater seem to be broken so my simple question is,
I think my stock 2009 Automatic GT/CS has 3.31 gears.
It is a weekend car and I like to mash it from time to time.
I have noticed off the line it is a little slugish but once it gets going
second gear pops in and all hell breaks loose.
So if I race someone there is a big difference between off the line and going from a roll.
If I change the gears in the forums expierience, how will this affect gears 2-5 during a race?

I'm toying with the idea of changing to 3.73 or 4.10's, But don't have a tuner yet to fix the speedo calibration. How much would the spedo be off with 3.73's? 4.10's?
I can't afford both right now so should I wait and get the tuner first and gears later or just get the gears and be careful?
Also, 2000 GT 5-speed, full bolt-ons except headers. I do a lot of highway driving. What gears do you recomend. I don't "fear the gear" just concerned about milage. I've considered going with 3.90's as a compromise, but can't seem to find those in the FRPP offering only those made by Motive. How do you feel about FRPP vs. Motive gears?

Motive makes most of Ford racing gears anyhow so don't worry about the brand. Also the gear calc will show you how far off your speedo will be compared to stock.

When I had my clutch replaced by a family friend who happens to own his own shop and races stock cars at a local level, he brought up the idea of gears. He suggested that I get 3.55's and I mentioned 4.10's to which he bit back and stated that they would make my engine "rev" much to high and I could potentially blow my engine. I didn't really have a moment to explain myself before getting shot down by him and my dad, who was also present, but I think this theory is a bit flawed.
Correct me if I'm wrong, but this is the way I believe it to be; 4.10's indeed will get me to redline much quicker but will not "blow my engine." Sure, if you romp on it in 1st and go into the red and keep it there, you have a very good chance of damaging your engine. So I believe what he simply meant was that I have a higher chance of redlining the car and thus damaging the engine.
The problem I have is that my dad is very dead-set in his ways and theories. He believes that things should still be done the way they were when he was growing up, and isn't open to accepting new ideas. He's also extremely gullable and if our family friend said something, he's likely to hold on to that as a definite no if I ever wanted to get gears.
I'm kind of ranting now, but I just wanted to make sure my understanding of gears was correct. If I remember correctly, our friend suggested either 3.55's or even 3.73's. Anything higher than that, and he said the engine would be "revving like crazy."

Your engine is only going to rev like crazy if you are stupid and sit there on the limiter. All gears do is let you accelerate faster. Will your cruising rpms be a few hundred rpms higher? yes. Will these extra rpms damage your motor? No.
Gears are not going to make you get into the "redline" zone and blow your motor. All you have to do is shift anyhow. Its really a pointless argument if you ask me.
Some people would **** there pants if they saw my rpms in my 54 MG on the highway. I cruise at 5k rpms in 4th at 72mph. Sit on that for a while.
This whole stupid thing with wearing your engine out faster with gears is retarded.

I would like to put my car on the bottle in the future (hopefully early next year) and did not find any hard answers on what gears to get for nitrous applications. I'm assuming 3.73's just as if the car was supercharged, but I'd like to hear a hard answer from you folks.
Nitrous, on a second thought, may be a while away, but I'd rather do gears only once and not change from 4.10's to 3.73's, for example.

If you want the most from the car at the track then 4.10's are what you want regardless. It more depends on what can you deal with rpm wise on the highway and what speed your willing to top out at in 4th gear. With a manual tranny in and 4.10s in our cars, depending on tranny (T45 or Tr3650) you will only be able to go 115-122mph tops in 4th gear. So think about all that stuff then choose what your looking for. For me I know my car is gonna trap more then 115mph so if I do run 4.10's then I will have to run a 28" tall tire at the track. Which isn't a big deal to me.

If you're a v6 you've got a 7.5 rear end.
Reasoning as to what? 4.10s on an auto? You'll go through the gear quicker like a manual would, improved track times, ect..
